Method.s of Combating the Pest. 



Opinions .iiflCr .-is to the dt'sl luetivo- 

 iit'.'^s of tlic iiiiHcpt'dcs, nr tliousand- 

 IcorjTo,! Moriiis. In n liullctiii issued by 

 the :M:iiyl;ind A;,Micnltui;il Experiment 

 Station, it is inaintaiiieil tli.at tlie insects 

 are not in the ii;il,it of fce.lin^r upon 

 healthy plant tissue an.l seldom attack 

 the stems of plants, but subsist chiefly 

 oil manure. .l<Mayin<r vegetable matter 

 or the humus in the soil, ami are espe- 

 cially fond of the yreeii ale^a that f^rows 

 on moist nower pots. The truth of that 

 contention, savs the bulletin, is attested 

 both iiy t\|irriineiits and by the struc- 

 ture of the insects' feedlnj; aj)j)aratus. 

 Th(> millepeibs' m;indibles. or .laws, are 

 not stroiij,' eiKuiffh to bite of!' hard j)arts 

 of plant tissue, l»ut the food must be 

 soft enou(,di to be scrajjed up. 

 _ IIo\\e\('r. it is admitted m the bulle- 

 tin that the millejiedes occasionally 

 molest sproutinji seeds and may be 

 starved intu attackino the tender roots 

 of som(^ jd;ints, damaging them to a 

 limited extent. And there is no doubt 

 tliat the insects are dis.agreeable, iiinvel- 

 come tenants when numerous. So the 

 Maryland A;,M-icultural K.xiiei iinent Sta- 

 tion undertook a series of tests of va- 

 rious methods of controlling the pest, 

 with residts that are here summarized. 



Certain \ri,'ctables, su(h as j^datocs 

 and carrot.*, are of the right texture to 

 suit the creatures' requirements and are. 

 among their fa\oritc foods. Hence, in 

 badly infcsteii houses, if slices of ])ota- 

 toes or carrots art! jdaced on the beds 

 in the evening, the under surfaces •will 

 lie found covered with millepedes the 

 following morning. A better way is to 

 place the bait in ;i small dejjrcssion in- 

 stead of on the surface and cover the 

 hoh> with a llower jtot or some such con- 

 venient object. Su(di tr;»[is will often 

 lie found jiartly tilled with mille|)edes, 

 which \\\\\ rtni;iin in these sheltered 

 [daces throughont the day instead of re- 

 treating to their galleries, as is their

usual custom. 'Nrillejtedes collected in 

 this manner can bo destroyed with boil- 

 ing water, kerosene or nicotine, or can 

 sim|dy be removed with a trowel and 

 crushed. W. E. liritton, state entomolo- 

 gist of Connecticut, recommends that a 

 hole be cut in a potato and the tuber 

 buried in thi> soil. .1. K. Sanders' de- 

 scrilu's a niidhod cmi)loyed in the green- 

 houses in Wisconsin; thin slices of car- 

 rots are placed under boards, and the 

 niillepedt's collected under tlu'in are 

 ciuslie<l. 



Ivxjieriments with jpoisoned baits, 

 howe\er, wei-e not successful at the ex- 

 ]ieriment station, although they have 

 been recommended as being (dlicient in 

 some localities. Bits of ]>otato were 

 dusted with powdered arsenate of lead, 

 Paris green or \Yhite arsenic, but the 

 millepedes fed on them only sparingly, 

 and none could be found that had been 

 injured by the jtoison. Su(di a method 

 might i>rove more effective where the 

 humus is not so abundant in the soil. 



Experiments with tobacco ])roducts 

 show that they are ])robably the best 

 material for the control of the green- 

 house millepede. 



Tobacco Dust. 



Tobacco dust s[)rinkled ou the beds 

 at the rate of ."iOU pounds to the acre, 

 or about one ounce tcj each nine square 

 fe(d, ju'o\ed f.'iiriy efVi'ctive. On the day 

 following suidi a treatment .about idghty- 

 live per cent of the milleitedes on the 

 beds were dead, although some appar- 

 ently noiinal indi\ iilu.'ils were moving 

 ai'fiund through the dust. Of the mille- 

 pedes btdow the surface, only about live 

 ]ier cent were dead. Specimens were as 

 numerous on the treated bench as on 

 the check ]dot. Two days later no mille- 

 jpe<les could b(> found on the surface, 

 and the nundier in the soil was about 

 half of th(! number found in the check 

 plots. No more dust was a])plied and 

 in a week conditions on the treated ]dot 

 were again normal. On another pbd 

 a secoioi dosage w;is given thret; days 

 after the tirst, with the result that at 

 the end of the week only about live per 

 cent of the former nundur remained. 



In a third experiirunt the tobacco 

 ilust ^vas worked into the soil instead of 

 being mercdy spiinkled on the surface, 

 'i'lie following morning one nnllejiede 

 w.as found \valking o\er the surface ami 

 four dead ones were dug up from below 

 the surface. All the otheis had ap-

jparently escajied to the check plots ad- 

 joining, for on these check plots the 

 niille]iedes were more numerous than 

 they had been previously. A few days 

 later milleiiedes were again found on 

 the treated jilot and by the end of a 

 week the infestation was normal. 



ir. A. Gossard, state entomologist of 

 Ohio, writes of a large swarm of mille- 

 jiedes that were injuring cucumbers: 

 *'An .abundance of tobacco dust was 

 used as a mulch about the ]dants and 

 ^jvithin a day or two the millepedes 

 H-ould be c(dlected from the concrete 

 tloors by the hundred thousands." 



In acldition to its insecticidal value, 

 tobacco dust is said to have some value 

 as a fertilizer. 



Nicotine Solutions. 



l'ort_\- per cent nicotine sulphate is 

 one of the best remedies to be used 

 against the millepedes. It can be ap- 

 jdied with good results at strengths 

 \arying from one part to 7;"tO i)art3 of 

 water to one part to 1,UUU parts of 

 w;iter. Notes on exjieriments with this 

 substance, diluted at the rate of one 

 ]i:irt of nicotine sulphate to 1,OOU parts 

 of water and aiiplied with a watering 

 can until the s(nl of the beds was thor- 

 oughly dreiK lied, show that aliout ninety 

 ]per cent of the milleiiecles were killed 

 by the ti-eatnient. Nearly every mille- 

 pede within three inches of the surface 

 was killed, but below that depth they 

 were .apiiarcntly unharmed. 



Practically the same results were se- 

 cured from "forty j>er cent nicotine solu- 

 tions as wire secured from the nicotine 

 sulphate. 



In the application of nicotine solu- 

 tions caie should be taken that all of 

 the soil is well drencheil with the ma- 

 terial. A light spraying will only be 

 efl'ective to a dejdh oi' about three-quar- 

 ters of an inch below the surface, but 

 if enough of the solution is j)ut on the 

 be<ls a few a j 'plications should rid the 

 house of this pest.
